semi-automatic union of the parts involving the invention.

Other objects of the invention will be apparent in the following description thereof.

Referring now to the accompanying drawing, forming part of this application and wherein like reference characters indicate like parts:

Figure l is a broken plan view of a blank for an egg carton to whichthe invention is applied, the view being approximately one-half full size.

Figure 2 is an end elevation of one of such cartons assembled and mounted upon means for assisting in its assembly.

Figure 3 is an elevation of the partition wall for such a carton.

The forming of such a carton from a blank of somewhat similar construction is well known in the art, and wherein the bottom member I of the blank is provided with a plurality of somewhat similar openings indicated at 2 for reception of protrusions extending from the bottom of a central division walls somewhat like that shown at 3, and a cover member 4 is provided with means for cooperatively engaging similar flangelike triangular corners 5 associated with the transverse partitions 6, when the carton is assembled.

However the instant invention resides particularly in the shape of the depending hook like members I of the division wall 3 in such a manner as to form an exceptionally strong and dependable association with the major holes 2 and minor holes 8 in the bottom member I of the carton. For this novel, combination the holes 8 are preferably of circular form and designed to register with the upwardly extending tit-like protrusion 9 of a plurality of the division wall hooks 1, after being first extended through the major openings 2 and then moved slightly longitudinally for such engagement.

In the embodiment here shown, which is that of an egg carton, it is preferred that but two of the hooked members I at each end of the division wall be provided with the tits 9, this being especially advantageous in the handling of the carton during the assembling of same, as it is found that when four of these hooks are ultimately engaged in their locked position the same quite suffices for the secure holding together of the carton, as the remaining hooks l0, between such titted ones, will assist only in the vertical separation of the parts of the carton.

As means to expedite the assembling of such a carton I have illustrated a wooden strip of somewhat angular form in cross-section and indicated at H, and which is of a length preferably equal or more than that of the carton, and having a slot or groove l2 in the upper central apex of same. Thus when the cartons are received for example by a retailer in their semiknocked down condition, that is with the marginal wall I3 carrying the otherwise free ends of the transverse division walls 3 is glued longitudinally the wall l3 and the partition wall 3 losely carried within same, the carton may be readily squeezed together and the partition wall 3 lowered upon the transverse walls centrally thereof with the hooks I protruding through the openings 2 and into the slot [2 in the temporary wooden form I I, when a very slight longitudinal movement of the partition wall 3 towards the minor openings 8 will effectively engage the division wall with the bottom I of the carton, resulting in its complete and very satisfactory assembly, ready for reception of the eggs, or other commodity, as the case may be.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

1. A collapsible egg carton made of a unitary blank and including, sides, a bottom, and trans.- verse partitions, a plurality of longitudinally alined spaced openings centrally of the bottom, a removable longitudinal central division wall, and hook-like members, spaced along the lower edge of said'division wall and extendable downwardly through certain of said spaced openings, and upwardly extending tits formed at the free ends of certain of said hook-like members, and adapted to register upwardly within certain others of said spaced openings.

2. A paper carton of the type described including sides, a bottom, and transverse partitions, a plurality of spaced openings centrally of the bottom thereof, a removable division wall having a plurality of spaced hook-like members lockably engageable through openings in the bottom, said bottom having auxiliary openings longitudinally aligned with said first mentioned openings, and upwardly extending tits formed at the free ends of certain of said hook-like members and adapted to register with said auxiliary openings whereby to augment said locking engagement.

3. A carton including sides, a bottom and a plurality of transverse partitions, all formed from a single blank, a separately formed longitudinal partition interfitting with said transverse partitions to divide the carton into cells, a plurality of spaced major and minor openings centrally of the bottom, and hook-like members spaced along the lower edge of said partition and extending through the major openings, certain of said hook- RUSSELL T.
